The degree to which Alison Krauss' fiddling has taken a back seat to her singing would be annoying if it weren't for the fact that hers is among the most enchanting voices in the history of bluegrass, or just about any genre for that matter. This collection touches most of the bases, though an instrumental wouldn't have hurt to flesh out the picture. There are three new songs to hook completists, and while Krauss fans will argue that this or that favorite song should have been here, it is fortunate that the Sugar Hill label allowed the inclusion of "I Don't Believe You've Met My Baby," originally on a Jerry Douglas album, since it is this writer's choice for Krauss' greatest vocal performance so far. Like Krauss, 14-year-old Cody Kilby is a contest winner, having won championships on banjo (his main ax), guitar, mandolin and dobro. "Down Home Pickin" is his first CD after two previous cassettes, and it is a doozy. He is a fiery picker, and the presence of Nashville virtuosi Sam Bush, Randy Howard, Carl Jackson and Roy Husky Jr. means that this is a disc any fan of instrumental bluegrass will want.
